The first working draft of XML:

Abstract
Extensible Markup Language (XML) is an extremely simple dialect of SGML
which is completely described in this document. The goal is to enable
generic SGML to be served, received, and processed on the Web in the way
that is now possible with HTML. For this reason, XML has been designed
for ease of implementation, and for interoperability with both SGML and
HTML.

So XML can rightly be seen as a child of SGML and therefore XHTML can
also.
